11. Claims. (01. 4-195) g The invention relates to wash fountains andmore particularly to an arrangement for the conduction of the drainagewater from the fountain and the supply of fresh water thereto.

Heretofore it has been customary to run the inlet water supply pipedirectly through the drain passage and form one of the joints for saidpipe in said passage which'under certain conditions will permit drainagewater finding its way into 10- -thesupply water passing to the sprayheador other 'point of use.- Also where the drain passage is associated witha trap and the supply water comes through a passage in the trap,defective castings may permit the supply water becoming 15 contaminatedwith water from the drain. In orderto-overcome the above mentioneddifiiculties the present invention has for its object to provideasupply-and drainage arrangement whereby the supply water is separatedfrom the drain gol water through an entirely separate passage'andthrough an air space between the supply and drainage passages. 1

The invention further consists in the several features hereinafter setforth and more particular1y defined by claims at the conclusion hereof.

Fig. 6 is a vertical sectional view through a wash fountain providedwith another form'of the invention;

Fig. 7 is a sectional view showing certain modifications of thestructure shown in Fig. 6;

Fig. 8 is a view similar to Fig. 7 showing another modification. uReferring to Fig. 1, the numeral I0 designates a basin which may be ofcircular, semi-circular, or other suitable form mounted on a support orpedestal ll.

A'tubular sprayhead supporting member I2 w having drain openings l3in'its' lower end seats on a spud l4 mounted in a recessed opening IS inthe bottom of the basin. The member l2 supports a sprayhead structure l6which may be similar to" that shown in the prior U. S". Patent designedto project a seriesof streams of water outwardlyand downwardly into thebasin.

A drain fitting I! has a'threaded opening IS in its upper end engagingthe lower threaded end of the spud I4, a circular chamber l9 formed insaid upper end, a passage 20 offset from one side of said chamber andextending downwardly and provided with a threaded lower end 2| en--gaging a drain pipe 22. The bottom of the chamber i9 is provided with'athreaded'opening 23 10 concentric with the opening l8 and adapted toreceive the lower end of a pipe or separator member 24 which extendsup'throug h the drain to a height somewhat above the height of thebasin' Hi, so that water from the drain will be prevented fromoverflowing through" said pipe evenlif the basin should become full ofwaste water.

It will'be noted that passage makes a curve from its point ofconnection'with the chamber Hi to its lower'end and that a boss isformed on the -wall of said passage inline with the open-v "ing 23' andadjacent a clearance space formed beneath the chamber I9. This boss25-is provided with a threaded'opening-26 adapted to receive thethreaded plug '21? formed on the lower end of an elbow fitting. 28 whichis provided. with a side opening into whichthe pipe 29 is threaded and atop openinghintowhich an upwardly extending supply pipe 30 is threaded;The pipe 29 may, besupplied with tempered water through a m; suitablehand controlled mixing valve 3| which hasa hot water connection 32 and acold water connection 33 leading thereto. The pipe 30 leads directly tothe sprayhead l6 and extends through the member. 24 from-ywhich it isspaced by an air gap, said member '24 normally keeping the drain waterfrom coming incontact with the inlet pipe connections including the pipe39 and fitting. 28, though'if any drainage water should getthroughbetween the member 24 and the drain fitting l'l, it will leakoutto atmosphere and will not be subjected to any pressures which mighttend to force-it intothe supply connections as has occurred where thesupply pipe passes directly through the drain passage and has a joint orjoints forming part of the wall of the drainpas sage.

In some instancesthe inlet. water supply pipe comes from above the basinand through a valve 5 located; below the basin and then up to thesprayhead, and in such instance the inlet connections may be arranged-asshown in *Fig'. 5 and associated with the .drain fitting [1. Ashereinshown in place of theelbow fitting 28,- I. useiarspecialfitting34,havinga partition;35 and provided with threaded openings 36, 31, 38,and 39. The inlet pipe from an overhead supply extends down to thepartition 35 and has threaded connection with the threaded opening 38.The water then passes through the space 4| to the pipe 42 connected withthe threaded opening 31 by which it is lead through a valve such as afoot controlledvalve, for example of U. S. Patent No. 2,085,824 of July6, 1937, and returns by way of pipe 43 connected with the threadedopening 36 to the space 44 from which it passes upwardly to thesprayhead through the pipe 45 connected to the threaded opening 39. Itis to be noted that the pipe 45 extends up through the separator pipe 24similar to the pipe 30 of the first described construction and isseparated from pipe 24 by an air gap. The fitting 34 has a threaded boss46 adapted to engage in the threaded opening 26 in the drain fitting IT.

In those instances where it is desirable to associate a trap directlywith the drain, the structure shown in Fig. 6 may be used. As shown thelower threaded end of the spud l5 connects with the threaded end 4'! ofa special trap fitting 68 which has the chamber 48' at its upper endconnected by an offset passage 49 to the trap or U-shaped portion 50which connects by a relatively straight passage 5! with an outletpassage 52, the passages 52 and 5! also connected with a vent passage 53having a threaded outlet 54 which is connected to an upwardly extendingvent pipe 55.

The water supply connection leading to the sprayhead, such as E6 of Fig.1, is formed in this instance between the pipe 55 and a pipe 56concentric therewith and connected to a manifold 51 whose lower end 58is sweated to said pipe 55 and has a laterally disposed inlet pipe 59connected thereto. The supply connection thus formed is completelyseparated from the drain passage including the member I2 through whichit projects by a pipe or separator member 60 which extends up to aheight above the top of the basin II] similar to the pipe 24 of thefirst described construction and at its lower end threads into a nut orthreaded plug member 6| which engages the opening 82 inthe wall 63 ofthe fitting 48 which opening is made large enough to allow the manifold51 to pass through, so that the vent pipe 55 may be screwed into place.

With this construction the inlet pipe is separated from the drain by thepipe 69 and an air space and has a fluid tight connection with the ventpipe 55.

Where it is not desired to mount the inlet manifold directly on the ventpipe, the modification shown in Fig. 7 may be used wherein the vent pipe55' is similar to the vent pipe 55 and the supply connection is formedby a manifold 51 and concentric pipes 58' and 56 in threaded engagementtherewith, said manifold having the supply pipe 59' connected thereto,the pipes 55', 58', and 56' and the manifold 51' adapted to besubstituted for the pipes 55, 56 and manifold 51 shown in Fig. 6, sothat the inlet connection including pipes 58' and 56' passes up throughthe pipe 60. It is to be noted that in this modified form the inletconnection is separate from the drain passage and from the ventassociated with the trap in said passage.

In those instances where an upwardly extending vent is providedassociated with a trap 48 and the supply comes from above the basin, thedetails of the inlet connections arranged as shown in Fig. 8 wherein thenumeral 55 designates the .vent pipe, and 64 an annular manifoldsurrounding said vent pipe and having pipes 65, 66, and 61 in threadedengagement therewith, the pipes 85 and 86 cooperating with the manifold64 to form an annular passage for conducting the inlet water downwardlyand having a threaded outlet 68 from which the water may be led througha control valve (not shown) and then conducted to the inlet 69 of anannular passage formed by the pipes 66 and B1 and the manifold. 64whereby the water is carried to the sprayhead such as the sprayhead I 6of Fig. 1, it being noted that the outer pipe 6'! is of a diameter tofit within the pipe 60 of Fig. 6 and be spaced therefrom.
